Vitalik Buterin posted on X stating that if we want to design synthetic stable assets, the real question to answer is not "how to stabilize against the dollar," but "what to stabilize against." He believes that the core need for users holding stablecoins is to lock in future spending ability, but if the crypto ecosystem is built on dollar-pegged stablecoins, it ultimately remains difficult to achieve true decentralization. Vitalik proposed that price indices could be established based on different regions, goods, and service categories, combined with prediction markets, allowing local large models to generate a basket of personalized prediction market positions based on individuals or businesses' future expenditure structures, representing "expected spending over the next several days." Under this concept, people can pursue appreciation with assets like ETH, stocks, etc., and when stability is needed, hold personalized assets linked to their own expenses instead of relying solely on the dollar.
